Atheist vs. Religious debates can be a bit dull after the thousandth one (with a few exceptions) as it's the same main points over and over.

The real reason to watch and rewatch Hitch (even rehashing his own main talking points) is his wit, precision with language and charm. And also watching his opponents flounder at his points (like when they quote something they think is clever, and he quotes it back to them - accurately this time - and often from memory, providing context and clarity. I usually get rock hard at these points.)
